NOTES TO FINANCIAL STATEMENTS

Note 1-Basis of Presentation

The consolidated financial statements include the accounts of CNB Corporation
("Company") and its wholly owned subsidiary, Citizens National Bank of Cheboygan
("Bank") and the Bank's wholly owned subsidiary CNB Mortgage Corporation. All
significant intercompany accounts and transactions are eliminated in
consolidation. The statements have been prepared by management without an audit
by independent certified public accountants. However, these statements reflect
all adjustments (consisting of normal recurring accruals) and disclosures which
are, in the opinion of management, necessary for a fair presentation of the
results for the interim periods presented and should be read in conjunction with
the notes to the financial statements included in the CNB Corporation's Form
10-K for the year ended December 31, 2003.

Certain information and footnote disclosures normally included in financial
statements prepared in accordance with accounting principles generally accepted
in the United States of America have been condensed or omitted pursuant to the
rules and regulations of the Securities and Exchange Commission.

Because the results of operations are so closely related to and responsive to
changes in economic conditions, the results for any interim period are not
necessarily indicative of the results that can be expected for the entire year.

Stock Compensation: The following proforma information presents net income and
basic and diluted earnings per share had the fair value method been used to
measure compensation for stock options granted. The exercise price of options
granted is equivalent to the market price of the underlying stock at the stock
grant date; therefore no compensation expense has been recorded for stock
options granted.

In future years, as additional options are granted, the proforma effect on net
income and earnings per share may increase. Stock options are used to reward
certain officers and provide them with an additional equity interest. Options
are issued for 10 year periods and have varying vesting schedules. Information
about options available for grant and options granted follows:

approximately 5.9 years. There were 22,507 options exercisable at March 31, 2004
with a weighted-average exercise price of $ 47.07.

There have been no significant changes in the Company's critical accounting
policies since December 31, 2003.

Note 2-Earnings Per Share

Basic earnings per share are calculated solely on weighted-average common shares
outstanding. Diluted earnings per share will reflect the potential dilution of
stock options and other common stock equivalents. For the three month period
ending March 31, 2004 the weighted average shares outstanding in calculating
basic earnings per share were 1,244,405 while the weighted average number of
shares for diluted earnings per share were 1,250,706. As of March 31, 2004 there
were 10,976 shares not considered in the earnings per share calculation because
they were antidilutive. For the three month period ending March 31, 2003 the
weighted average shares outstanding in calculating basic earnings per share were
1,247,727 while the weighted average number of shares for diluted earnings per
share were 1,250,878.

LOANS

Loans at March 31, 2004 increased $ 2.3 million from December 31, 2003. The
table below shows total loans outstanding by type, in thousands of dollars, at
March 31, 2004 and December 31, 2003 and their percentages of the total loan

concentration. However, all tourism related businesses, when combined, total
11.2% of total loans.

The Company maintains a high level of asset quality as a result of actively
managing delinquencies, nonperforming assets and potential loan problems. The
Company performs an ongoing review of all large credits to watch for any
deterioration in quality. Nonperforming loans are comprised of: (1) loans
accounted for on a nonaccrual basis; (2) loans contractually past due 90 days or
more as to interest or principal payments (but not included in nonaccrual loans
in (1) above); and (3) other loans whose terms have been renegotiated to provide
a reduction or deferral of interest or principal because of a deterioration in
the financial position of the borrower (exclusive of loans in (1) or (2) above).
The aggregate amount of nonperforming loans is shown in the table below.

RESULTS OF OPERATIONS

CNB Corporation's 2004 net income for the first three months was $ 773,000 a
decrease of $ 216,000 compared to 2003 results. This decrease can be partially
attributed to a decline in interest income due to the low rate environment.
Also, the decrease can be attributed to the decline in refinance activity and
the resulting decline of gains on the sale of loans the Company experienced at
March 31, 2004 compared to March 31, 2003. Basic earnings per share and diluted
earnings per share were $0.62 per share for 2004 compared to $0.79 for 2003. The
return on assets was 1.22% for the first three months of the year versus 1.58%
for the same period in 2003. The return on equity was 12.12% compared to 15.70%
for the same period last year.

For the first three months of 2004, net interest income was $ 2.3 million
representing a decrease of 8.6% from the same period in 2003. This decrease can
be attributed to a greater decline in interest income compared to interest
expense for the first three months of 2004. Net interest margin decreased to
3.84% for the quarter ending March 31, 2004 compared to 4.32% for the period
ending March 31, 2003. This change can be attributable to a decline in overall
interest rates from 2003 to 2004.

Noninterest income for the three months ending March 31, 2004 was $ 383,000 a
decrease of $ 64,000 or 14.3% from the same period last year. This decrease can
be attributed to a decline in the number of loans sold to the secondary market
which in turn decreased the gain on sale of loans received. Noninterest expense
for the first three months of 2003 was $ 1.6 million, the same as 2003. The
decline in the income tax expense for the Company during the first three months
of 2004 compared to 2003 resulted from lower income before tax and from a
decline in tax exempt interest income which increased the effective tax rate by
2% compared to 2003.

ITEM 3-QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The primary source of market risk for the financial instruments held by the
Company is interest rate risk. That is, the risk that a change in market rates
will adversely affect the market value of the instruments. Generally, the longer
the maturity, the higher the interest rate risk exposure. While maturity
information does not necessarily present all aspects of exposure, it may provide
an indication of where risks are prevalent.

All financial institutions assume interest rate risk as an integral part of
normal operations. Managing and measuring interest rate risk is a dynamic,
multi-faceted process that ranges from reducing the exposure of the Company's
net interest margin to swings in interest rates, to assuring sufficient capital
and liquidity to support future balance sheet growth. The Company manages
interest rate risk through the Asset Liability Committee. The Asset Liability
Committee is comprised of bank officers from various disciplines. The Committee
reviews policies and establishes rates which lead to prudent investment of
resources, the effective management of risks associated with changing interest
rates, the maintenance of adequate liquidity, and the earning of an adequate
return of shareholders' equity.

Management believes that there has been no significant changes to the interest
rate sensitivity since the presentation in the December 31, 2003 Management
Discussion and Analysis appearing in the December 31, 2003 10K.
